Fantom [35]

Answer:

b. False

Explanation:

All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). These intermediary products are produced at the glycolysis and citric acid cycle stage.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Hence, during respiration, most ATP is formed as a direct result of the net movement of protons down a concentration gradient but not potassium against a concentration gradient potassium.

Explain the difference between positive and negative control over transcription. drag the appropriate items to their respective
hammer [34]
The type of control is described by the response of the operon when no regulatory protein is extant. In the case of negative regulator, the genes in the operon are distinct unless they are switched off by a repressor protein. Therefore the operon will be turned on essential (the genes will be prcise) when the repressor in inactived. In the case of positive control, the genes are distinct only when an active regulator protein, an activator, is present, Thus the operon will be turned off when the positive regulatory protein is missing or inactivated.

G If we (humans) do not have enough oxygen to allow aerobic respiration to occur, what will happen? Group of answer choices
ohaa [14]

Answer:

We will produce lactate/lactic acid through fermentation.

Explanation:

During strenuous activities, muscle cells do not sufficient supply of oxygen to meet the energy requirements. As a result, anaerobic respiration occurs to temporarily supply energy and lactic acid is produced instead of carbondioxide and water.

Lactic acid accumulates in muscles and eventually preventing further contraction. The muscle cells are said to have incurred an 'oxygen dept' since they have used up more energy than was possible from the oxygen supplied to them. The largest amount of lactic acid a body of a trained athlete can tolerate is about 127grams, and the largest tolerable oxygen is about 16 litres.
